Apparatus for manipulating image pixel streams to generate an output image pixel stream in response to a selected mode

DETAILED DESCRIPTION It is, therefore, an object of the present invention to provide apparatus for combining streams of data.
It is another, more specific object of the present invention, to provide apparatus for combining streams of data in a plurality of different ways.
These and other objects of the present invention are realized in circuitry which transfers data in streams in which a plurality of individual discrete groups of data are all addressed to the same address, where the circuitry includes apparatus for manipulating the data appearing in streams comprising a manipulation engine responsive to some portion of each group of the data transferred to cause the data to be manipulated in a particular manner such as by multiplying the data by a value or combining it with the data in another stream of data.
These and other objects and features of the invention will be better understood by reference to the detailed description which follows taken together with the drawings in which like elements are referred to by like designations throughout the several views.
